[B]i did this intercooler setup a year ago it give 60 horse to the wheels call me for any oither questions

 

yeah, post the dyno.

In the BMW M3 aftermarket world, the addition of an air-to-water aftercooler adds about 50hp (from 350 to about 400 crank hp) to a centrifugally blown M3 (Comptech uses a centrifugal blower too). The sytem includes a small air-to-water unit, a water pump, and a front mounted water to air unit (ie, a small radiator).

The pressure drop is fairly low, below 1 psi. But, with the cooler charge, you can jump the boost from 6 to around 9 psi.

A real benefit of the unit is safety, by using a cooler intake charge, likelihood of detonation is reduced, making it safer in extreme temps/track usage, but the added power due to (i) the denser charge, and (ii) increased boost pressure is great too.

The above-described design is far from ideal, however, as a front mount air to air intercooler is more effective. But, b/c of the physical positioning of the blower unit and plumbing issues, it is very difficulte to run an air-air intercooler as a turbo unit uses.

Drawing conclustions from experience with M3's, I think that 50-60hp for addition of a properly designed aftercooler/intercooler with attendant boost increase could reasonably be expected.

 

The most affordable solution is to implement an Aquamist sprayer in the intake path, feeding your intake with a water/alcohol spray. Effective to dramatically reduce your intake temperatures, improve power, reduce knock, and clean your head/valves. The downside is that you have to keep a water tank full, although you can easily drop ice water in the tank for even better combustion.

The system has been employed by many in the supercharger field, mainly in amercican muscle cars running positive displacement blowers, like Roots and Lysholm-type units. An acquaintance of mine just puchased one for his blown M3, but has yet to install it.

I think the Aquamist system cost around $600, but it's not a turn-key kit. . .just the basic pump and injectors I believe. You have to figure out the plumbing and water tank, and tank location.

Maybe you could get comptech to work on a system?
